This tool is legit... I cleaned this coil last week but it was still running hot.  I've had the SHAECO fin straightener from in my possession now for a while and finally had a chance to use it today, it simply attaches to an oscillating tool. They recommended using some soap bubbles then a comb after to straighten them out. BigBlu was what was used. I used the new 860i to perform a before and after on the coil and it dropped approximately 6⁰F.

SureSwtich over view... Through my testing of this device, it has proven valuable.  When I installed mine 5 years ago, I put my contactor in a drawer just in case.  It's still there. The Copeland SureSwitch is a solid state contactor with sealed contacts, it provides additional compressor protection from brownouts. My favourite feature of the SureSwitch is that it is designed to prevent pitting and arcing through its control function.

Old school will tell you to run it for an hour... But when you truly pay attention, time is not the indicator of a complete evacuation.  This 20 ton system was pulled down in 20 minutes by pulling the cores and using 3/4" hoses. This allowed me to use a battery powered vac pump and avoided running cords on a commercial roof. I used the NP6DLM pump and NH35AB 3/4" hoses and NVR2 core removal tool.

Thermistor troubleshooting... We're using the ICM Controls UDefrost control to show a little thermistor troubleshooting.  The UDefrost is a heat pump defrost control that has a customized set up through the ICM OMNI app. A thermistor is a resistor that changes resistance due to a change in temperature.  In the video we are using an NTC (negative temperature coefficient).  This means the resistance will drop on a rise in temperature.  PTC (positive temperature coefficient) has a rise in resistance with a rise in temperature.

Packaged Window Heat Pump... Midea RAC designed this Window Package Heat Pump for high rise buildings in New York City. Word on the street is tenant spaces in some areas will have a max temp they can be at, just like they have a min temp they must maintain.  Essentially, some rented spaces will be forced to provide air conditioning if they don't already. I think the atmomized condensate is a cool feature.

It builds a barrier to moisture... There's a few manufacturers that do this, York also but it's a one piece harness.  From time to time, I see the terminal box melted from moisture penetration. What has really helped is silicone grease, it prevents moisture from getting inside the connection. I'm using silicone grease on this Lennox unit.  It's dielectric and won't pass current.
